Definitions

  • This invention relates to a machine for making cartons of cardboard such as corrugated sheet and, more particularly, to a cardboard feeder for use with the carton making machine which achieves smooth feeding of cardboards without causing aefective feeding, collapse, and the like.
  • fig. 4 is a schematic diagram of a conventional cardboard feeder 1.
  • cardboards 5 are piled and stored in a hopper formea by a front stopper member 3 and a rear support member 4 provided on a table 2.
  • a slide bar 6 embedded sliaably in the table 2 is reciprocated by a crank mechanism 7.
  • a kicker 8 is fixed on the slide bar 6 so that in response to the operation of the crank mechanism 7 the cardboaras 5 in the hopper are kicked out in the airection of the arrow shown in the drawing through a slit formed at the lower end of the front stopper member 3 of the hopper each lowest one at a time.
  • Fig. 5 is an enlarged front view of a portion A in Fig. 4.
  • the upper feed roll 9 is divided into plural segments ama supportea rotatably, while the surface of the lower feed roll 10 is finished through knurling or made rough by forming it by rubber, for example.
  • a ariving system of tne upper and lower feea rolls 9 and 10 is not illustrated.
  • FIG. 6 illustrates the state in which the cardboard 5 passes between the upper and lower feed rolls 9 ana 10.
  • a gap g between tne upper and lower feed rolls 9 and 10 is set by a gap adjusting unit provided separately, but not illustrated, so as to assume a spacing smaller tnan the thickness T of tne cardboard 5.
  • the gap g between the upper and lower feed rolls 9 ana 10 had to be made considerably smaller than the thickness T of the cardboard 5 because the friction drag is of the static type and relatively large.
  • the degree of collapse of the caraboara 5 see tne shaded portions of Fig. 6 ) becomes large and the strength of a carton thus made is insufficient; thus, disqualified products tend to be manufactured many.
  • corrugated board of thick linerboara configuration had to be employed and this in turn caused another inconvenience, such as a waste of resources.
  • tne conventional cardboard feeder had tne problems that to draw out the lowest cardboard out of those storea in tne hopper it is necessary to increase the pinching force of the upper and lower feed rolls, this tends to cause collapse of the caraboard just conveyed, ana to prevent such collapse the raw caraboara must be thick.
  • the present invention resides in a cardboard feeder naving upper and lower feed rolls for gripping and senaing cardboards toward a subsequent step ana a kicker, characterized by rolls aisposed so as to contact with the unaer surface of the cardboard which rotate in synchronization with tne operation rate of tne kicker only when the Kicker operates in tne feea direction of the cardboard.
  • the rolls interlocked with gears accommodating ratchets therein are rotated only in the feed direction of the caraboard to thereby apply a feea force to the under surface of the lowest one of the cardboards in a hopper.
  • FIG. 1 is a schematic siae view of a caraboara feeaer according to an emboaiment of the present invention
  • FIG. 2 is a sectional view taken in the airection of the arrows B-B of Fig. 1.
  • a cardboard feeaer indicated by reference numeral 1 functions as a device for kicking out forwara the lowest one of caraboaras 5 pilea in a hopper formed by a front stopper member 3 and a rear support member 4 proviaed on a table 2 by the use of the reciprocating motion of a Kicker 8 projecting from tne upper surface of the table 2.
  • the cardboard tnus Kicked is pinched between a pair of upper and lower feed rolls 9 and 10 disposed in a station subsequent to tne cardboard feeder 1, so that it is forcealy taken and sent out.
  • the kicKer 8 is fixed on a sliae bar 6 sliaable inside the table 2 so that it can reciprocate together with this slide bar 6.
  • the sliae bar 6 in turn is reciprocated by means of a crank mechanism 7 disposed therebelow.
  • the foregoing configuration of the device is similar to the conventional cardboard feeder shown in Fig. 4.
  • rolls 11 are included which form an important portion of the present invention.
  • gears 12 are securea on either end of each roll 11.
  • the roll 11 is arranged so that its upper point is substantially flush with the surface of the table 2.
  • the gear 12 a ratchet mechanism is accommodated for rotating the shaft of the roll in one airection, that is, in the embodiment illustrated these are designed so that the roll 11 can rotate only in the feed direction of caraboaras.
  • Reference numeral 13 indicates a gear whose upper point is in gear with the gear 12 accommodating the ratchet mechanism with its lower point being in dear with a rack 14 proviaed unuersiae the slide bar b .
  • the embodiment illustrated in Figs. 1 and 2 includes six gears 12 each accommodating the ratchet mechanism therein provided on either side of the cardboard feed station, i.e. six rolls 11 arranged in parallel with one another, the number of rolls may be one or more and as shown in Fig. j, a roll composea of a plurality of short rolls lla supported by one shaft may be employed in place of one long roll 11.
  • the rolls 11 are provided in the table 2 with their upper points being substantially flush with the upper surface of the table 2, the rolls 11 are driven only when the Kicker 8 moves forward ( only at the time of kicking out the cardboard 5 ), ana the top speed of the kicker 8 is set so as to coincide substantially with the peripheral speed of the rolls 11; thus, the friction drag caused by the face of the table 2 is reduced and tne caraboara 5 KicKea out by the kicxer 8 can be sent forwara by a small force even while it is conveyed by the upper and lower feea rolis 9 and 10, consequently, the card- boara 5 is collapsed little ana a processing in tne subsequent step can be performed accurately, thereby resulting in the auvantages of enhancing the product quality ana of saving resources.
  • the cardboards are sent out smoothly from insiae the hopper; thus, a waste of resources and a fall of strength of products that woula otherwise result from collapse of the cardboard can be prevented from arising, and the degree of accuracy of printing, grooving, ana like processes done in the subsequent step can be improvea.
